Will I run into problems using a Chorus 9 speed crankset and chainrings and BB with Chorus 10 speed rear der and shifters? If so, can I just switch chainrings or will I run into optimum chainline problems? Thanks!
No problems -- new chainrings would be slightly better (nm)TJeanloz

This is what Branford bike says about it...

"8/9 speed and 10 speed rings - Unlike Shimano, Campagnolo did not change their crankset or chainrings when they went from 8 to 9 speed. Thus, all Campy 8 or 9 speed cranks may be used with 8 or 9 speed cassettes and chains.
To convert any Campy 8 or 9 speed two ring crank to 10 speed two ring crank, all you need to do is replace the outer chainring. Bolts, arms and the inner ring are all the same for 8, 9 or 10 speed."

Seems that Shimano changed the inner to go from 8 to 9 and Campy changed the outer to go 9 to 10. That's it.
